Actually, the question was rather different: which is the *actual* 
representation
used by one specific implementation, that is the GNU C++ compiler? I know
what the standard says in general about this, but, having noticed that 
even for an
empty enum the underlying type appear to be 4-bytes wide, I wondered whether
smaller underlying types are ever used in our implementation...

... but, it's not a big deal: we have got more serious issues ;)
